[Alfentanil for neuroleptanesthesia in short operations]

Alfentanil, a potent short acting analgetic, is used for short operations instead of fentanyl as a neurolept anaesthesia agent. The action of this form of anaesthesia is described. As initial dose of alfentanil we used 25 micrograms/kg b.w. The total dose of alfentanil for operations of about 30 min on average was 40 micrograms/kg b.w. Blood pressure, heart rate and side effects of this form of anaesthesia have been investigated.
